Arc flash Assessment
Protect your workforce. Minimize risk. Ensure compliance.
Arc flash incidents are among the most serious hazards in electrical systems—capable of causing catastrophic injuries, system damage, and unplanned downtime. At Curious Engineering Consulting, we conduct comprehensive arc flash studies to help Illinois businesses meet compliance standards and protect both personnel and infrastructure.
-
An arc flash analysis evaluates your facility’s electrical system to identify and quantify the risk of arc flash events—sudden energy discharges caused by faults. We calculate incident energy levels, define hazard boundaries, and recommend safety measures including appropriate PPE, helping you comply with NFPA 70E and OSHA requirements.

Electrical System Risk Evaluation
We conduct a thorough analysis of your electrical distribution system to pinpoint potential arc flash hazards. This proactive approach helps you reduce risk and maintain compliance with safety regulations.
Accurate Electrical One-Line Diagrams
Our team develops precise one-line diagrams that provide a clear and detailed representation of your electrical infrastructure. These diagrams improve system understanding and are essential tools for emergency shutoff, lockout/tagout procedures, and ongoing maintenance planning.
Safety-Compliant Equipment Labeling
We apply durable, standards-compliant arc flash labels to all evaluated equipment. Each label includes essential safety information, including the required personal protective equipment (PPE) and incident energy levels, helping workers stay informed and protected.
Identification and Reduction of High-Risk Panels
In addition to standard arc flash assessments, we focus on locating high-risk panels and components within your system. Our experts recommend practical mitigation strategies, such as protective device upgrades, system reconfiguration, or improved insulation, to significantly lower arc flash risk.
Results-Driven Reporting and Consultation
Our service goes beyond technical analysis—we provide a comprehensive review of your assessment results. Through clear explanations and strategic planning, we work with you to implement effective safety improvements based on real-world insights.
Control Panels & Automation
Smart design. Seamless integration. Long-term reliability.
We offer custom control panel design and automation solutions for Illinois businesses looking to increase productivity, reduce downtime, and improve system safety. Our engineers work directly with facility teams to understand your operations and deliver systems that are tailored to your exact requirements.
All panels are built to UL 508A standards using trusted brands like Rockwell Automation and Siemens, ensuring top-tier performance and maintainability.
Our Automation Services Include:
Custom control panel design
PLC programming & integration
HMI design
Industrial automation upgrades
Troubleshooting & optimization
As a single-source partner for both panels and automation in Illinois, we reduce project complexity, speed up delivery, and ensure all system components work in harmony.
Maximize uptime. Improve electrical safety. Stay compliant.
Our coordination studies ensure that protective devices in your electrical system—such as circuit breakers and fuses—are properly configured to isolate faults without triggering unnecessary system-wide shutdowns.
A poorly coordinated system can result in avoidable outages, equipment damage, or safety hazards. Our team analyzes your entire electrical network to optimize device settings and ensure each component performs its protective function without compromising the rest of the system.
From large industrial campuses in Chicagoland to mid-size operations in Central and Southern Illinois, we bring both regional insight and national expertise to every project.
